Starting in Amroth and ending in St Dogmaels, Pembrokeshire’s Coastal Path in south west Wales was recently named the third best walk in the world. We’ll explore all 186 miles of this National Trail in S4C’s new series, Llwybr yr Afrordir, which starts on Monday. Leading us through the journey will be writer and broadcaster Jon Gower from Llanelli, naturalist Elinor Gwynn, and poet and scholar Damian Walford Davies.
